Answer: 
will not occur.
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
A general single displacement reaction can be represented as :
a)
Flourine is more reactive than chlorine and hence this reaction cannot occur.
b) 
Sodium is more reactive than zinc and hence the reaction will occur.
c) 
Iron is more reactive than copper and hence the reaction will occur.
d) 
Magnesium is more reactive than hydrogen and hence the reaction will occur.
Most likely the second one (sand letting water run through it) because if you are trying to determine how what moves through soil You would want the one the one that can do that:)
A refractometer is an instrument used to measure the refractive index of gases, liquids, and translucent solids like gemstones. Liquids are tested for things such as blood proteins, salinity, fluid concentrations, and specific gravity of urine.
Yes because condensed milk and
evaporated milk are similar to one another. However, there won't be the same sweet flavor but the texture is the same.
Answer:
A
Explanation:
The answer is A) because the A container has tightly packed molecules but not as tight as C so that means A is liquid, and C is a solid which makes B a gas
